You can search the database for flight or "on the wing" data on a Species,
Genus or Common Name. Such data is useful in determining when peak
activity times occur and can be used in a wide range of applications:

Conservation activities can be timed to have least impact on the adult and
breeding populations

Niche Partitioning. That is, different species have different peak
activity times to avoid overexploitation of food resources

Pollination Studies

Field work or nature studies can be timed to coincide with peak activity
time. This would be extremely important if you were studies a particular
species.
